Medication errors in veterinary anesthesia: a literature review.

OBJECTIVE: To provide an overview of medication errors (MEs) in veterinary medicine, with a focus on the perianesthetic period; to compare MEs in veterinary medicine with human anesthesia practice, and to describe factors contributing to the risk of MEs and strategies for error reduction. DATABASES USED: PubMed and CAB abstracts; search terms: [("patient safety" or "medication error∗") AND veterin∗]. CONCLUSIONS: Human anesthesia is recognized as having a relatively high risk of MEs. In veterinary medicine, MEs were among the most commonly reported medical error. Predisposing factors for MEs in human and veterinary anesthesia include general (e.g. distraction, fatigue, workload, supervision) and specific factors (e.g. requirement for dose calculations when dosing for body mass, using several medications within a short time period and preparing syringes ahead of time). Data on MEs are most commonly collected in self-reporting systems, which very likely underestimate the true incidence, a problem acknowledged in human medicine. Case reports have described a variety of MEs in the perianesthetic period, including prescription, preparation and administration errors. Dogs and cats were the most frequently reported species, with MEs in cats more commonly associated with harmful outcomes compared with dogs. In addition to education and raising awareness, other strategies described for reducing the risk of MEs include behavioral, communication, identification, organizational, engineering and cognitive aids.

Guideline No. 445: Management of Chronic Pelvic Pain.

OBJECTIVE: To provide evidence-based recommendations for the management of chronic pelvic pain in females. TARGET POPULATION: This guideline is specific to pelvic pain in adolescent and adult females and excluded literature that looked at pelvic pain in males. It also did not address genital pain. BENEFITS, HARMS, AND COSTS: The intent is to benefit patients with chronic pelvic pain by providing an evidence-based approach to management. Access to certain interventions such as physiotherapy and psychological treatments, and to interdisciplinary care overall, may be limited by costs and service availability. EVIDENCE: Medline and the Cochrane Database from 1990 to 2020 were searched for articles in English on subjects related to chronic pelvic pain, including diagnosis, overlapping pain conditions, central sensitization, management, medications, surgery, physiotherapy, psychological therapies, alternative and complementary therapies, and multidisciplinary and interdisciplinary care. The committee reviewed the literature and available data and used a consensus approach to develop recommendations. Only articles in English and pertaining to female subjects were included. VALIDATION METHODS: The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and conditional [weak] recommendations). INTENDED AUDIENCE: Family physicians, gynaecologists, urologists, pain specialists, physiotherapists, and mental health professionals. TWEETABLE ABSTRACT: Management of chronic pelvic pain should consider multifactorial contributors, including underlying central sensitization/nociplastic pain, and employ an interdisciplinary biopsychosocial approach that includes pain education, physiotherapy, and psychological & medical treatments. SUMMARY STATEMENTS: RECOMMENDATIONS.

Unlocking dynamic root phenotypes for simultaneous enhancement of water and phosphorus uptake.

Phosphorus (P) and water are crucial for plant growth, but their availability is challenged by climate change, leading to reduced crop production and global food security. In many agricultural soils, crop productivity is confronted by both water and P limitations. The diminished soil moisture decreases available P due to reduced P diffusion, and inadequate P availability diminishes tissue water status through modifications in stomatal conductance and a decrease in root hydraulic conductance. P and water display contrasting distributions in the soil, with P being concentrated in the topsoil and water in the subsoil. Plants adapt to water- and P-limited environments by efficiently exploring localized resource hotspots of P and water through the adaptation of their root system. Thus, developing cultivars with improved root architecture is crucial for accessing and utilizing P and water from arid and P-deficient soils. To meet this goal, breeding towards multiple advantageous root traits can lead to better cultivars for water- and P-limited environments. This review discusses the interplay of P and water availability and highlights specific root traits that enhance the exploration and exploitation of optimal resource-rich soil strata while reducing metabolic costs. We propose root ideotype models, including 'topsoil foraging', 'subsoil foraging', and 'topsoil/subsoil foraging' for maize (monocot) and common bean (dicot). These models integrate beneficial root traits and guide the development of water- and P-efficient cultivars for challenging environments.

Unveiling the regulatory of miR-101-3p on ZNF746 in a Parkinson's disease cell model: Implications for therapeutic targeting.

In this study, we explored the regulatory role of microRNA miR-101-3p on the zinc finger protein 746 (ZNF746), also known as PARIS, which is implicated in both sporadic and familial forms of Parkinson's disease. In a Parkinson's disease cell model, utilizing SH-SY5Y cells treated with 1-methyl-4-phenylpyridine (MPP+), we observed that miR-101-3p was downregulated, while ZNF746 was upregulated. To investigate the direct impact of miR-101-3p on ZNF746, our team conducted overexpression experiments, successfully reversing ZNF746's expression at both the mRNA and protein levels, as confirmed through quantitative PCR and western blotting. We also performed luciferase assays, providing compelling evidence that ZNF746 is a direct target of miR-101-3p. Additionally, we noted that miR-101-3p overexpression resulted in increased expression of PGC1α, a gene targeted by ZNF746. Functionally, we assessed the implications of miR-101-3p overexpression through MTS assays and flow cytometry, revealing significant promotion of cell viability, inhibition of ROS production, and reduced apoptosis in the Parkinson's disease cell model. In conclusion, this study highlights the role of miR-101-3p in regulating ZNF746 expression and suggests its potential as a therapeutic target for Parkinson's disease. These findings provide valuable molecular insights that could pave the way for innovative treatment strategies in combating this debilitating neurodegenerative disorder.

New platinum (II) complexes based on schiff bases: synthesis, specification, X-ray structure, ADMET, DFT, molecular docking, and anticancer activity against breast cancer.

Acylpyrazolone-based Schiff base ligands (HLn) and their corresponding Pt(II) complexes with the general formula [Pt(Ln)(Cl)] (n = 1-3) were synthesized and characterized by different spectroscopic techniques including 1H-NMR, 195Pt-NMR, LC-Mass, FT-IR, and UV-Vis spectroscopy, as well as elemental analysis. The crystal structure of one of the Schiff base ligands was also obtained. Based on the ADMET comparative results and the bioavailability radar charts, the complexes are completely drug-like. The Schiff base complexes with a structural difference of one methyl group in ligand were used as anticancer agents against human breast cancer cell lines SKBR3 and MDA-MB-231. The IC50 values after treatment by [Pt(L1)Cl] and [Pt(L2)Cl] were obtained more than cisplatin and less than carboplatin on cancer cells MDA-MB-231 and SKBR3, while the IC50 value of [Pt(L3)Cl] was more than both other complexes and clinical Pt drugs. Molecular docking data showed that the groove binding is the main interaction with DNA double strands with a minor contribution from electrostatic interactions. To investigate the structure-activity relationship, DFT computational was done. All quantum chemical parameters display the drug approaching biomacromolecule and more biological activity of [Pt(L1)Cl] > [Pt(L2)Cl] > [Pt(L3)Cl]. So, three Schiff base platinum complexes can be suitable candidates as anticancer drugs. Schiff-base ligands (HLn) and their Pt(II) complexes ([Pt(Ln)(Cl)], n=1-3) were obtained. To investigate their biological property and main interactions with DNA, ADMET, and cytotoxicity against MDA-MB-231 and SKBR3, DFT, and Molecular docking were done.

Cardioembolic stroke, the most common subtype of stroke in COVID 19: A single center experience from Isfahan, Iran.

Background: Some studies showed the cerebrovascular manifestation in patients with recently pandemic coronavirus 2 named the coronavirus disease 2019 (COVID-19). However, there are rare reports about stroke subtypes in these patients. Here, we reported the stroke subtype in patients with laboratory-confirmed diagnosis of COVID-19 and treated at our hospitals, which are located in Isfahan, Iran. Materials and Methods: This is a retrospective, observational case series. Data were collected from March 01, 2020, to May 20, 2020, at three designated special care centers for COVID-19 of Isfahan University of Medical Sciences. The study included 1188 consecutive hospitalized patients with laboratory-confirmed diagnosis of COVID-19. Results: Of 1188 COVID-19 patients, 7 (0.5%) patients developed stroke. Five (0.4%) had ischemic arterial stroke, 1 (0.08%) hemorrhagic stroke and 1(0.08 %) cerebral venous and sinus thrombosis. Sixty percent of ischemic stroke were cardioembolic stroke (CE) and the rest 2 (40%) were embolic stroke of undetermined source. Three male patients (40%) had stroke as a presenting and admitted symptom of COVID-19. Four patients (57%) had severe COVID-19. Conclusion: Stroke was an uncommon manifestation in COVID-19 patients. CE was a common subtype of stroke in COVID-19 patients in our centers.

The Effects of Resveratrol on Silica-Induced Lung Oxidative Stress and Inflammation in Rat.

Background: Chronic exposure to silica is related with the provocation of an inflammatory response and oxidative stress mechanism. Vitamin D has multiple benefits in biological activities particularly respiratory system disease. Method: In this research, 20 male Wistar rats were randomly allocated into four groups (5 rats /group) as follow: Group1 received saline as (negative control) group. The group 2 received a single IT instillation of silica (positive control) group; the group 3 was co-administrated with single IT silica and Vitamin D (20 mg/kg/day) daily for a period of 90 days. The rats of group 4 received Vitamin D daily for a period of 90 days. Results: Silica significantly increased serum and lung total Oxidant Status (TOS). Meanwhile, silica reduced serum and lung total antioxidant capacity (TAC), GSH and tumor necrosis factor-α (TNF-a). Vitamin D treatment meaningfully reversed oxidative stress, antioxidants status and inflammatory response. Also, Vitamin D improved histopathological changes caused by silica. Conclusion: These findings indicate that Vitamin D exerts protective effects against silica-induced lung injury. It seems that Vitamin D has potential use as a therapeutic object for silica induced lung injure.

Post marketing new adverse effects of oral therapies in multiple sclerosis: A systematic review.

BACKGROUND: There is a lack of safety information about the post-marketing adverse effects of several disease-modifying drugs (DMDs) used to control multiple sclerosis (MS). Investigating the post-marketing side effects is required to manifest the safety of the appropriate therapy. Therefore, the present systematic review aimed to identify disease-modifying drugs used to control multiple sclerosis attacks and progress. METHODS: The Web of Science, PubMed, and Scopus databases were searched for studies published until November 2020 based on the research strategy terms. Inclusion criteria involved all full texts exploring disease-modifying drugs used to control multiple sclerosis based on case reports and case series studies. The Joanna Briggs Institute (JBI) critical appraisal checklist was used to assess the quality of case report studies. RESULTS: In total, 25 articles that met the criteria for inclusion were retrieved in the present systematic review. The most side effects were observed with fingolimod and teriflunomide, respectively, while dimethyl fumarate had minor side effects. CONCLUSION: The oral therapies have some significant post-marketing adverse effects that have been diagnosed in numerous case reports. Some of them are serious and must be noticed by neurologists. Accordingly, in this review, we assessed the post-marketing adverse effects of oral therapies for multiple sclerosis.

Effects of L-carnitine supplementation in patients with mild-to-moderate COVID-19 disease: a pilot study.

BACKGROUND: The present single-center clinical trial was designed to evaluate the potential benefits of L-carnitine supplementation in patients with COVID-19 disease. METHODS AND PATIENTS: The study was conducted on 75 patients with mild-to-moderate COVID-19 hospitalized in Shahid Beheshti Hospital-Hamadan, IRAN. The participants were randomly divided into intervention (n = 32) and control groups (n = 43). The control group received their standard hospital treatment only. In addition to standard medications, the intervention group received 3000 mg oral L-carnitine daily in three divided doses for five days. The blood samples were collected and para-clinical parameters were measured at the beginning and end of the treatment. Clinical outcomes were also recorded, and data were analyzed using χ2 and t-tests. RESULTS: Higher means of O2 saturation were observed in the intervention rather than in the control group. Mean erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were significantly lower in the intervention group. Furthermore, mean alkaline phosphatase (ALP) activity and lactate dehydrogenase (LDH) were lower in the intervention group. Also, lower mean serum creatine phosphokinase (CPK) was observed in the intervention group. No significant differences were observed in terms of clinical symptoms; however, six patients (14%) in the control group died due to the complications of COVID-19, while all patients in the intervention group survived. CONCLUSION: Taken together, L-carnitine can be considered as a drug supplement in patients with COVID-19.

Differential metabolic rearrangements in the roots and leaves of Cicer arietinum caused by single or double nitrate and/or phosphate deficiencies.

Nitrate (NO3 - ) and phosphate (Pi) deficiencies are the major constraints for chickpea productivity, significantly impacting global food security. However, excessive fertilization is expensive and can also lead to environmental pollution. Therefore, there is an urgent need to develop chickpea cultivars that are able to grow on soils deficient in both NO3 - and Pi. This study focused on the identification of key NO3 - and/or Pi starvation-responsive metabolic pathways in the leaves and roots of chickpea grown under single and double nutrient deficiencies of NO3 - and Pi, in comparison with nutrient-sufficient conditions. A global metabolite analysis revealed organ-specific differences in the metabolic adaptation to nutrient deficiencies. Moreover, we found stronger adaptive responses in the roots and leaves to any single than combined nutrient-deficient stresses. For example, chickpea enhanced the allocation of carbon among nitrogen-rich amino acids (AAs) and increased the production of organic acids in roots under NO3 - deficiency, whereas this adaptive response was not found under double nutrient deficiency. Nitrogen remobilization through the transport of AAs from leaves to roots was greater under NO3 - deficiency than double nutrient deficiency conditions. Glucose-6-phosphate and fructose-6-phosphate accumulated in the roots under single nutrient deficiencies, but not under double nutrient deficiency, and higher glycolytic pathway activities were observed in both roots and leaves under single nutrient deficiency than double nutrient deficiency. Hence, the simultaneous deficiency generated a unique profile of metabolic changes that could not be simply described as the result of the combined deficiencies of the two nutrients.

The protective effect of resveratrol on diazinon-induced oxidative stress and glucose hemostasis disorder in rats' liver.

This study was intended to assess the possible protective effect of resveratrol (Res) against oxidative stress and glucose hemostasis disorder in rats exposed to diazinon (DZN) for 4 weeks. Totally 25 Sprague-Dawley rats were divided randomly into five groups: Control (orally received corn oil), DZN group (orally received 70 mg/kg/day), and Res groups (received DZN 70 mg/kg/day plus Res doses of 5, 10, and 20 mg/kg bodyweight/-day), respectively. DZN significantly inhibited serum acetylcholinesterase enzyme (Ach E), serum and liver catalase, glutathione peroxidase activities, also total antioxidant capacities. On the other hand, DZN increased serum and liver malondialdehyde. DZN significantly increased Forkhead box protein O1 (Foxo1) expression and decreased phosphatase and tensin homolog (PTEN) and sirtuin 1 (Sirt-1) expression. DZN impaired glucose hemostasis. Instead, Res treatment significantly reversed status of oxidative stress and antioxidant enzymes activities induced by DZN. Also, Res improved glucose hemostasis. Res increased PTEN and Sirt-1 expression and reduced Foxo1 expression. Res administration ameliorated liver histopathological changes induced by DZN. These data confirmed that DZN significantly enhances oxidative stress and impairs glucose hemostasis. While Res showed a protective effect against the toxicity induced by DZN in rats.

Synthesis and crystal structures of new mixed-ligand schiff base complexes containing N-donor heterocyclic co-ligands: Molecular docking and pharmacophore modeling studies on the main proteases of SARS-CoV-2 virus (COVID-19 disease).

Three new mixed-ligand copper(II) complexes (1-3) with NN'O type unsymmetrical tridentate Schiff base ligands (SB) and N-donor heterocyclic co-ligands, with general formula [Cu(SB)(L)]ClO4, were synthesized and characterized using single crystal x-ray diffraction (SCXRD), FT-IR and UV-Vis spectroscopy and elemental analyses. The SB ligand is the half-unit form of the condensation of 1,3-propanediamine with 5-methoxysalicylaldehyde and the co-ligands (L) are pyridine (py in (1)), 2,2'-bipyridine (bpy in (2)) and 1,10-phenanthroline (phen in (3)). Crystal structures of (2) and (3) were obtained by SCXRD. Molecular docking and pharmacophore studies were performed to study the interactions between the synthesized complexes and SARS-CoV-2 virus main proteases (PDB IDs: 6LU7, 6WQF and 6W9C). Results revealed that complex (3) with phen co-ligand showed better docking scores with the three receptors, i.e. 6LU7 (-8.05 kcal.mol-1), 6W9C (-7.70 kcal.mol-1) and 6WQF (-7.75 kcal.mol-1). The order of the binding best energies for (3) was also as follows: 6LU7 > 6WQF > 6W9C. All of the studied complexes showed considerable performance, comparable to the standard drug, Favipiravir.

Simultaneous silencing of the A2aR and PD-1 immune checkpoints by siRNA-loaded nanoparticles enhances the immunotherapeutic potential of dendritic cell vaccine in tumor experimental models.

Following various immunotherapies, lack of proper anti-tumor immune responses is considered a significant problem in novel cancer therapeutic approaches. The expression of inhibitory checkpoint molecules on tumor-infiltrating T cells is one of the main reasons for the ineffectiveness of various immunotherapies. Therefore, we decided to inhibit two of the most important immune checkpoints expressed on tumor-associated T cells, PD-1 and A2aR. Ligation of PD-1 with PD-L1 and A2aR with adenosine significantly suppress T cell responses against tumor cells. Whitin tumors, specific inhibition of these molecules on T cells is of particular importance for successful immunotherapy as well as the elimination of treatment-associated side-effects. Thus, in this study, superparamagnetic iron oxide (SPION) nanoparticles (NPs) were covered by chitosan lactate (CL), functionalized with TAT peptide, and loaded with siRNA molecules against PD-1 and A2aR. Appropriate physicochemical properties of the prepared NPs resulted in efficient delivery of siRNA to tumor-derived T cells and suppressed the expression of A2aR and PD-1, ex vivo. T cell functions such as cytokine secretion and proliferation were considerably enhanced by the downregulation of these molecules which led to an increase in their survival time. Interestingly, treatment of CT26 and 4T1 mouse tumors with siRNA-loaded NPs not only inhibited tumor growth but also markedly increased anti-tumor immune responses and survival time. The results strongly support the efficacy of SPION-CL-TAT NPs loaded with anti-PD-1/A2aR siRNAs in cancer therapy and their further development for cancer patients in the near future.

Evaluating the efficacy of intranasal oxytocin on pain and function among individuals who experience chronic pain: a protocol for a multisite, placebo-controlled, blinded, sequential, within-subjects crossover trial.

INTRODUCTION: Current treatments for chronic pain (eg, opioids) can have adverse side effects and rarely result in resolution of pain. As such, there is a need for adjuvant analgesics that are non-addictive, have few adverse side effects and are effective for pain management across several chronic pain conditions. Oxytocin is a naturally occurring hormone that has gained attention for its potential analgesic properties. The objective of this trial is to evaluate the efficacy of intranasal oxytocin on pain and function among adults with chronic pain. METHODS AND ANALYSIS: This is a placebo-controlled, triple-blind, sequential, within-subject crossover trial. Adults with chronic neuropathic, pelvic and musculoskeletal pain will be recruited from three Canadian provinces (British Columbia, Alberta and Newfoundland and Labrador, respectively). Enrolled patients will provide one saliva sample pretreatment to evaluate basal oxytocin levels and polymorphisms of the oxytocin receptor gene before being randomised to one of two trial arms. Patients will self-administer three different oxytocin nasal sprays twice daily for a period of 2 weeks (ie, 24 IU, 48 IU and placebo). Patients will complete daily diaries, including standardised measures on day 1, day 7 and day 14. Primary outcomes include pain and pain-related interference. Secondary outcomes include emotional function, sleep disturbance and global impression of change. Intention-to-treat analyses will be performed to evaluate whether improvement in pain and physical function will be observed posttreatment. ETHICS AND DISSEMINATION: Trial protocols were approved by the Newfoundland and Labrador Health Research Ethics Board (HREB #20227), University of British Columbia Clinical Research Ethics Board (CREB #H20-00729), University of Calgary Conjoint Health Research Ethics Board (REB20 #0359) and Health Canada (Control # 252780). Results will be disseminated through publication in peer-reviewed journals and presentations at scientific conferences. TRIAL REGISTRATION NUMBER: NCT04903002; Pre-results.

Different T cell related immunological profiles in COVID-19 patients compared to healthy controls.

In various pathological conditions, cellular immunity plays an important role in immune responses. Amongimmunecells, T lymphocytes pdomotecellular and humoralresponses as well as innate immunity. Therefore, careful investigation of these cells has a significant impact on accurate knowledge in COVID-19diseasepathogenesis. In current research, the frequency and function of various T lymphocytes involved in immune responses examined in SARS-CoV-2 patients with various disease severity compared to normal subjects. In order to make an accurate comparison among patients with various disease severity, this study was performed on asymptomatic recovered cases (n = 20), ICU hospitalized patients (n = 30), non-ICU hospitalized patients (n = 30), and normal subjects (n = 20). To precisely evaluate T cells activity following purification, their cytokine secretion activity was examined. Similarly, immediately after purification of Treg cells, their inhibitory activity on T cells was investigated. The results showed that COVID-19 patients with severe disease (ICU hospitalized patients) not only had a remarkable increase in Th1 and Th17 but also a considerable decrease in Th2 and Treg cells. More importantly, as the IL-17 and IFN-γ secretion was sharply increased in severe disease, the secretion of IL-10 and IL-4 was decreased. Furthermore, the inhibitory activity of Treg cells was reduced in severe disease patients in comparison to other groups. In severe COVID-19 disease, current findings indicate when the inflammatory arm of cellular immunity is significantly increased, a considerable reduction in anti-inflammatory and regulatory arm occurred.

Changes in oxidative markers in COVID-19 patients.

AIM AND BACKGROUND: Covid-19 has been as an important human infectious disease that has affected several countries. Cytokine storm has major role is Covid-19 pathogenesis. The association between inflammation and oxidative stress is well stablished. In this article, we aim to assess oxidative stress markers in Covid-19 patients compare to the healthy subjects. METHOD: A total of 48 persons (24 with Covid-19 and 24 controls) were evaluated in this research. Serum oxidative stress markers including Malondialdehyde (MDA), total oxidant status (TOS), activity of catalase (CAT) and super oxide dismutase (SOD) were measured alongside routine laboratory tests. RESULTS: Patients group were divided into ICU and Non-ICU groups. ESR, CRP and serum level of ferritin were significantly higher in case group. Serum level of albumin was significantly lower in Covid-19 patients. Serum MDA and TOS was significantly increased in Covid-19 patients. Also, Covid-19 patients had higher serum activity of CAT and GPX. CONCLUSION: Oxidative stress markers are significantly elevated in Covid-19 patients. This may have significant role in mechanism of disease development. In the fight against Covid-19, as a global struggle, all possible treatments demand more attention. So, Covid-19 patients may benefit from strategies for reducing or preventing oxidative stress.

Genotype- and tissue-specific physiological and biochemical changes of two chickpea (Cicer arietinum) varieties following a rapid dehydration.

In nature, plants may suffer rapid dehydration (RD), which causes significant loss of the annual global chickpea production. Thus, ascertaining more knowledge concerning the RD-tolerance mechanisms in chickpea is crucial for developing high drought-tolerant varieties to assure sustainable chickpea production under sudden water deficit. Here, we focused on genotype-driven variation in leaf relative water content (RWC) and associated differences in RD-responsive physiological and biochemical attributes in roots and leaves of two chickpea varieties, FLIP00-21C and FLIP02-89C, subjected to well-watered and RD conditions. FLIP00-21C showed higher RD-tolerance than FLIP02-89C, evident by its higher leaf RWC during RD. Consistently, FLIP00-21C exhibited lower membrane injury due to lower hydrogen peroxide (H2 O2 ) accumulation than FLIP02-89C during RD, indicating reduced RD-induced oxidative damage. Under RD conditions, total phenolics in roots and flavonoids in roots and leaves increased more in FLIP02-89C compared to FLIP00-21C; however, the increased activities of superoxide dismutase and H2 O2 -scavenging enzymes were more properly coordinated in FLIP00-21C than in FLIP02-89C, which might contribute to more efficient antioxidant defense in FLIP00-21C than in FLIP02-89C. The higher leaf RWC of FLIP00-21C versus FLIP02-89C under RD might be associated with greater increases in the levels of the osmo-regulators proline and total free amino acids (TFAAs) in FLIP00-21C than in FLIP02-89C. Collectively, the higher RD-tolerance of FLIP00-21C is mainly associated with the maintenance of higher RWC, stronger antioxidant defense, and greater accumulation of proline and TFAAs. These traits could be useful for evaluating the drought-tolerance of chickpea varieties and further marker-assisted breeding approaches for improvement of chickpea productivity.

Phosphate or nitrate imbalance induces stronger molecular responses than combined nutrient deprivation in roots and leaves of chickpea plants.

The negative effects of phosphate (Pi) and/or nitrate (NO3- ) fertilizers on the environment have raised an urgent need to develop crop varieties with higher Pi and/or nitrogen use efficiencies for cultivation in low-fertility soils. Achieving this goal depends upon research that focuses on the identification of genes involved in plant responses to Pi and/or NO3- starvation. Although plant responses to individual deficiency in either Pi (-Pi/+NO3- ) or NO3- (+Pi/-NO3- ) have been separately studied, our understanding of plant responses to combined Pi and NO3- deficiency (-Pi/-NO3- ) is still very limited. Using RNA-sequencing approach, transcriptome changes in the roots and leaves of chickpea cultivated under -Pi/+NO3- , +Pi/-NO3- or -Pi/-NO3- conditions were investigated in a comparative manner. -Pi/-NO3- treatment displayed lesser effect on expression changes of genes related to Pi or NO3- transport, signalling networks, lipid remodelling, nitrogen and Pi scavenging/remobilization/recycling, carbon metabolism and hormone metabolism than -Pi/+NO3- or +Pi/-NO3- treatments. Therefore, the plant response to -Pi/-NO3- is not simply an additive result of plant responses to -Pi/+NO3- and +Pi/-NO3- treatments. Our results indicate that nutrient imbalance is a stronger stimulus for molecular reprogramming than an overall deficiency.
